Join us in the beautiful resort town of McCall, Idaho for a 100 mile race that is alpine to the core. Starting and finishing at rustic Burgdorf Hotsprings resort, the race will tackle the trails and summits of this premiere mountain playground. Crossing 8 high passes and gaining around 22,000 feet, this world class course was crafted to be tough and breathtakingly scenic. In 2018, IMTUF will run a clockwise loop, and changes direction each year.
